Biofuels continue to contribute to the attainment of the energyrelated goals of the United States, including increasing energy security and reducing the environmental degradation linked to transportation fuels. Demand for biofuel production will increase as new technologies are deployed and adopted by producers and consumers. The composition of feedstock for biofuel production, such as grain, will continue to grow. But when grain production has reached full capacity, alternative feedstocks will be needed to meet demand. The potential economic implications of biofuel production are wide-ranging and warrant further attention, especially in rural areas where the feedstocks originate.
